ABSTRACT: The intention of this work is to mark out the literature survey of water pollution of Buriganga River. Themethod used for this write-up is a survey of scholarly journal articles, web materials, academic books, conference papers, project reports and freely accessible materials on the Buriganga river water pollution. All previouswriters whose works werechecked,concurredon water pollution and spatial variation of physicochemical parameters over time and location more than other sources in terms of both chemical and physical water toxins that shownuplifted values of majorchemical parameters (lead, cadmium, chromium, copper and some anions) beyond the acceptable/lower limits set by administrative bodies. Authors also agreed on the issuethat human, aquatic and physical environment are in alarming situation due to rising values of chemical parameters. From the survey and analyzing the output of past studies, we can conclude that Buriganga river is polluted and water must be treated before use both fordomestic and industrial purposes to avoid the spread of epidemics. Proposals of the scrutiny incorporate: (1) consistentsurvey of Buriganga river water pollution; (2) strict organization of directions water quality benchmarks and (3) Well-planned monitoring of the environments of water bodies by authorities and the local people.

INTRODUCTION Quality of water notices to the factor of water, which is to be shown at the perfect level for satisfactory development of humans, plants and animals. Differentparameters like temperature, turbidity, nutrients, hardness, alkalinity, dissolved Oxygen play an imp erative part for creatures in the water body, on the other hand biological Oxygen demand, chemical Oxygen demand appear the contamination level of the water. In normal aquatic framework, different chemical parameters happen in truncated concentration.This concentration increases as a result of fast development of urbanization, diversification of industrial activities, ill treatment of natural resources and lack of environmental management. Figure 1:Buriganga river from Google map *Corresponding Author:AmenaFerdousi1 | Page Assessment of heavy metals and water quality parameters of Buriganga river of Dhaka, .. Buriganga is a black river streams past the southwest edges of Dhaka city, the capital of Bangladesh, which plays a vital part for the capital. This river gets all sorts of domestic wastes through junks outfall, unprocessed sewage being discharged into the Buriganga River. Each day Dhaka’s 12.6 million individuals create about 3,200 tons of solid litter, most of which goes into the stream. And every day up to 40,000 tons of unprocessed tannery waste is discharged specifically into the waterway [1], which contains different natural and inanimate supplements and other poisons. These toxins cannot be extracted due to its ephemeral character and hence they are gathered in the river system gradually. Most distributed information on the impacts of toxins on aquatic organisms however gives the report of antagonistic impacts at concentration higher than worthy constrain (GESAMP, 1985)[2]. The following review article portrays the outcomes of the work accomplished by different analysts in the past on the heavy metal contamination and water quality parameters of river Buriganga. II. WATER QUALITY PARAMETERS AND HEAVY METAL POLLUTION On the bank of Buriganga river, 343 tannery industries are situated[3]. Tanneries in the city's Hazaribagh rangereleasea few 21,600 square meters of liquid wastes regular into the Buriganga River [4].These deleterious effluents, including chromium, lead, Sulphur, ammonium, salt and other materials, are extremely contaminating the Buriganga River [5].Adjacent to the Buriganga river near jingira, karanigang ranges, 627 dyeing industries are located [6].Theseindustries discharge 5000 square meters of effluents each day into the Buriganga river.These effluents are consisted of some harmful chemicals such as epoxy, polyurethane, enamel, ductile-silvery white metal,hydrochloric acid, alkalis, lime, caustic soda, aluminum, zinc chromate, zinc phosphate, asbestos etcetera[7].Besides all, 104 notable fertilizer industries are inFatulla, Faridabad, Bosilla, Damraadjacent to Buriganga River and these industries are liable for discharging approximately 9000 square meters of effluentseveryday into the Buriganga River [7]. Over 80,000 cubic meters of untreated industrial wastes are dumped every day into the Buriganga. Tens of thousands of people are using the Buriganga riverways every day to and from different far-flung areas of the country’s southern districts, including greater Barisal, Bhola, Patuakhali and Chandpur boarding on several launches through Sadarghat point in the old part in the capital. [9].Therefore, further study is required to evaluate the existing water quality of this river. Figure2: Distinctive water grade parameters of Buriganga River in Winter, Summer and Autumn. (Note: Source: Ahammed et al. (2016)) Ahammed et al. (2016) studied the water grade of Buriganga -a river streaming through Dhaka [10].The water gradevariables specify that the standard of water in Buriganga river is very imperfect.The measurement of average DO, BOD and COD was 1.11 mg/L, 82.30 mg/L and 148.45 mg/L respectively and the accumulation of nitrate and phosphate was 5.92 mg/L and 5.83 mg/L respectively. Nitrate and phosphate values are from a non-point source of pollution while the DO, BOD and COD show that these values are more symbolic of point sources of pollution. Ahmed et al. (2011) investigated physicochemical properties of tannery and textile Effluents and surface water of river Buriganga and Karnatoli, Bangladesh [11].As well as he analyzed the physicochemical properties such as Biological Oxygen Demand (BOD), salinity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Sodium (Na+), Potassium (K+), Calcium (Ca2+), Iron (Fe3+), Phosphate (PO ), Chloride (Cl-), *Corresponding Author:AmenaFerdousi2 | Page Assessment of heavy metals and water quality parameters of Buriganga river of Dhaka, .. Nitrite (NO ) and Nitrate (NO3) of tannery effluent.The seven variables in the tannery and textile effluents are immoderate than the DoE Standard suggested for open water, however, only BOD5 these values were within range in the surface water of Buriganga rivers.

Investigation of water grade parameters at various points in the Buriganga River have been analyzed by Akbor et al. (2017) [13]. The analysis described that the water of Buriganga river is highly concentrated in biological oxygen demand (BOD), chemical oxygen demand (COD), Electrical conductivity (EC), Total dissolved solid (TDS), Salinity, Alkalinity, Turbidity and little in dissolved oxygen (DO). Fatema et al. (2018) scrutinized water grade evaluation of the river Buriganga, Bangladesh [14]. This analysis reveals that the water grade of the river Buriganga is being contaminated from its neighboring point and non-point roots with local wastewater and liquid waste that is sent out from different factories. Constantly strict observing of water grade is mandatory to protect the Buriganga river. Figure 7:Heavy metals of Buriganga River(Note: Source: Mokaddesetal. (2013)). Figure 8: Average water gradevariables in water of Buriganga River. (Note: Source: Mokaddes et al. (2013)). Hafiz et al. (2017) explored assessment of instream flow requirement based on oxygen demand of Dhaka peripheral river system [15]. Authors have found the maximum monthly BOD varies from 11.51 to 23.40 mg/l in pre-monsoon, from 3.35 to 4.54 mg/l in monsoon and from 3.36 to 18.67 mg/l in post-monsoon in the Turag river.

Sequential extraction procedure was employed in sediment samples for the geochemical partitioning of the metals. Total trace metal content in water and sediment samples were analyzed and compared with different standard and reference values. Concentration of total chromium, lead, cadmium, zinc, copper, nickel, cobalt and arsenic in water samples were greatly exceeded the toxicity reference values in both season. Concentration of chromium, lead, copper and nickel in sediment samples were mostly higher than that of severe effect level values, at which the sediment is considered heavily polluted. On average 72 % chromium, 92 % lead, 88 % zinc, 73 % copper, 63 % nickel and 68 % of total cobalt were associated with the first three labile sequential extraction phases, which portion is readily bioavailable and might be associated with frequent negative biological effects.

  • Aquatic Ecology and Dangerous Substances: Bangladesh Perspective

E-mail: [email protected] ; Phone: +880 2 9354128 ; Fax: +880 2 8315394 Bangladesh had always been predominantly and agricultural based country and in early days pollution was never even felt in this region. Since early sixties, of necessity, industries of various kinds started to spring up slowly. It appears in a survey that ecological imbalance is being caused continuously due to discharge of various industrial wastes into air and water bodies. It has also been found that the intensity of pollution caused by the factories and industrial units depend on their type, location, raw materials, chemical effects, production process and discharge of gaseous, liquid and solid pollutants to the natural environment. All of Bangladesh's sewage and industrial wastes are flushed directly into Ganges and Brahmaputra Rivers. There are wide spread fears that as the region develops in industrial infrastructure, industrial pollution will accelerate, compounding the problems posed by raw municipal wastes. About 900 polluting industries in Bangladesh dispose of untreated industrial wastes directly into rivers, although the effluents contain 10 to 100 times the allowable levels permissible for human health. The Ganges-Brahmaputra delta is the largest delta in the world and the rivers contribute one-third of the global sediment transport to the world oceans. The rivers flow through 10 per cent global population and carry untreated rural, urban, municipal and industrial wastes to the Bay of Bengal.

  • Analysis of the Causes and Impacts of Water Pollution of Buriganga River: a Critical Study
    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 2, ISSUE 9, SEPTEMBER 2013 ISSN 2277-8616 Analysis Of The Causes And Impacts Of Water Pollution Of Buriganga River: A Critical Study Chandan chakraborty, Md Mazaharul Huq, Sobur Ahmed, Taslima Tabassum, Md. Rubel Miah Abstract: When water becomes contaminated by unexpected substances, it is considered as harmful for human and aquatic lives. This water is termed as polluted water. Various causes are responsible for polluting water. Some natural causes are mixture of biodegraded portion of animal and plants to pure water, siltation by erosion of river banks etc. Domestic wastes, industrial wastes, fertilizers etc. are man-made pollutants of water. The state of sur- face and ground water pollution in Bangladesh is alarming. Especially the Buriganga is largely polluted by Dhaka city. Necessity of water for each and every living beings needs no description. They intake water directly or indirectly for physiological activities. If this in taking water is polluted, it will do harm that is for sure. The worst part is, this bad impact transports to others through food chain. Therefore, we must be aware of the adverse influence polluted water may have on us. At present, we cannot prevent water being polluted cent percent, but minimization is very much needed. It is time we took some steps to start working on it.

Ashiqur Rahman and Dhia Al Bakri Faculty of Agriculture, Food and Natural Resources, The University of Sydney, NSW 2006 Australia Abstract: The Buriganga river system is located in the southern part of the north central region of Bangladesh, passing through west and south of Dhaka, the capital of Bangladesh. The river receives wastewater from numerous numbers of sources along its way, which are discharged as industrial effluents, municipal sewage, household wastes, clinical wastes and oils. The purpose of this study is to investigate into the impact of this wastewater on the river water and thus to provide an updated report on the state of water quality of the river Buriganga. The water samples were collected in year 2008-09 during both dry and wet seasons from different points along the river and analysed for various physiochemical quality parameters, which includes: temperature, pH, EC, DO, BOD5 , COD, PO 43 -P, NH -N, Pb and Cr. The mean values for the parameters in both dry and wet seasons were compared with the surface water quality standards as set by the Department of Environment (DOE) in Bangladesh. The water quality test results have also been summarised and presented through box and whisker plots.

  • Spatial Assessment of Water Quality in Peripheral Rivers of Dhaka City for Optimal Relocation of Water Intake Point
    Spatial Assessment of Water Quality in Peripheral Rivers of Dhaka City for Optimal Relocation of Water Intake Point Sayma Rahman Tennessee Technological University Cookeville, TN 38505-0001 Email: [email protected] Submitted to: ESRI USER’s Conference Abstract In order to meet the ever increasing demand of drinking water, Dhaka Water Supply Authority (DWASA) of Bangladesh has installed a number of deep tube wells that tap the upper aquifers. However, in most parts of the city, the current groundwater abstraction exceeds the recharge rate, causing the groundwater to be mined systematically and be depleted of its finite reserve. The present rate of depletion is alarming because it can potentially cause environmental hazards such as land subsidence, prolonged water logging, alteration in vegetation etc. Thus, there is an urgent need to alleviate the demand on the upper aquifers and explore more sustainable sources to augment the present water supply. This implies a conjunctive use of groundwater and surface water in order to maintain the balance between anthropogenic demand and water’s natural availability. However, the surface water along these peripheral rivers is known to be highly polluted due to municipal and industrial untreated wastewaters that are discharged. This study analyzes the present water quality scenario along the surrounding rivers of Dhaka City pertaining to a 2-day field survey during the dry season of 2005. It uses GIS as a tool to arrive at an optimal solution for relocation of the current intake point for surface water withdrawal. Derivation of water quality profiles (as a function of distance) along the downstream and upstream reaches of the current intake location indicated that a new location 12 km upstream of the present intake point could potentially be ideal for withdrawing surface water during the monsoon season.
